Photoionization - Wikipedia
网页Photoionization is the process that makes once-invisible filaments in deep space glow. [1] Photoionization is the physical process in which an ion is formed from the interaction of a photon with an atom or molecule. [2]
Photo-ionization | Photoelectron, Electron Emission, Photon
网页photo-ionization, the interaction of electromagnetic radiation with matter resulting in the dissociation of that matter into electrically charged particles. The simplest example, the photoelectric effect (q.v.), occurs when light shines on a …
Photoionization | Basics, Processes & Effects
网页2024年5月29日 · Photoionization is a fundamental physical process wherein an atom or molecule absorbs a photon of light, causing an electron to gain enough energy to escape from the atom or molecule. This phenomenon is crucial in various scientific fields including astrophysics, atmospheric science, and spectroscopy.
Photoionization - an overview | ScienceDirect Topics
网页Photoionization is a powerful method used in analytical and spectroscopic applications, such as mass spectrometry and photoionization spectroscopy. It involves the generation of molecular cations by ionizing a neutral species with the help of photons, which enables the study of specific quantum states and the analysis of photoelectron spectra.
Photoelectrochemical process - Wikipedia
网页Photoionization is the physical process in which an incident photon ejects one or more electrons from an atom, ion or molecule. This is essentially the same process that occurs with the photoelectric effect with metals.
